   The intermediate results of the operation performed by this routine
   are buffered in a temporary vector which is later moved to the output
   vector.  Thus vout can be actually be vin if desired without
   interfering with the computation.

<h4><a name="Examples">Examples</a></h4>
<PRE>
   Let

      m1 = |  0.  1.  0. |   and  vin = | 1. |
           |             |              |    |
           | -1.  0.  0. |              | 2. |

           |  0.  0.  1. |              | 3. |

   Then the call

      <b>mxv_c</b> ( m1, vin, vout );

   produces the vector

      vout = |  2. |
             |     |
